Dihydroactinidiolide is a pheromone for a variety of insects;^[2] for example, it is one of the three components of the pheromone for queen recognition of the workers of the red fire ant.^[3]

As with nepetalactone, found in catnip, dihydroactinidiolide is a cat attractant. Cultivators of silver vine (which contains another such chemical, actinidine, which is also a cat attractant) sometimes find their plants destroyed by enthusiastic cats.
